摘　　要：为提高长期服役玻璃幕墙的安全性,以隐框玻璃幕墙为研究对象,分析结构胶损伤(即脱胶)对幕墙力学性能的影响规律。为提高有限元模拟准确度,建立隐框玻璃幕墙整体有限元模型,模型包括玻璃面板、结构胶、铝合金框架,分析8种不同结构胶损伤工况对幕墙风荷载下应力和位移、自振频率和振型的影响规律,并在此基础上为幕墙损伤识别提供依据和建议。To improve the safety of glass curtain walls under long-term service,this paper carries out study of effect mechanism of structural adhesive damage(i.e.exfoliation)on mechanical characteristics of hidden frame glass curtain walls.A whole finite element model of hidden frame glass curtain wall is established to improve the numerical accuracy,which includes glass panel,structural adhesive and aluminum alloy frame.Considering eight different structural adhesive damage cases,the effects of damage on mechanical characteristics are analyzed,including stress and displacement under wind loads,natural frequencies and vibration modes.Based on the study,the support and suggestions are given for damage identification of hidden frame glass curtain walls.
